Bathroom

This article is about private rooms for personal hygiene. For toilet facilities outside the home, see public toilet. For private toilet room at a residence, see toilet (room). For washing facilities outside the home, see public bathing.

A bathroom is a room in the home or hotel for personal hygiene activities, generally containing a toilet, a sink (basin) and either a bathtub, a shower, or both. In some countries, the toilet is usually included in the bathroom, whereas other cultures consider this insanitary or impractical, and give that fixture a room of its own. The toilet may even be outside of the home in the case of pit latrines. It may also be a question of available space in the house whether the toilet is included in the bathroom or not.

Historically, bathing was often a collective activity, which took place in public baths. In some countries the shared social aspect of cleansing the body is still important, as for example with sento in Japan and the "Turkish bath" (also known by other names) throughout the Islamic world.

In North American English the word "bathroom" may be used to mean any room containing a toilet, even a public toilet (although in the United States this is more commonly called a restroom and in Canada a washroom).

A residential bathroom in the US, with a shower, with rail-less screen and no bathtub, and a toilet.

The term for the place used to clean the body varies around the English-speaking world, as does the design of the room itself. A full bathroom is generally understood to contain a bath or shower (or both), a toilet, and a sink. An ensuite bathroom or ensuite shower room is attached to, and only accessible from, a bedroom. A family bathroom, in British estate agent terminology, is a full bathroom not attached to a bedroom, but with its door opening onto a corridor. A Jack and Jill bathroom (or connected bathroom) is situated between and usually shared by the occupants of two separate bedrooms. It may also have two wash basins.[1][2] A wetroom is a waterproof room usually equipped with a shower; it is designed to eliminate moisture damage and is compatible with underfloor heating systems.

In the United States, there is a lack of a single, universal definition; this commonly results in discrepancies between advertised and actual number of baths in real estate listings. Bathrooms are generally categorized as "master bathroom", containing a shower and a bathtub that is adjoining to the largest bedroom; a "full bathroom" (or "full bath"), containing four plumbing fixtures: a toilet and sink, and either a bathtub with a shower, or a bathtub and a separate shower stall; "half (1/2) bath" (or "powder room") containing just a toilet and sink; and "3/4 bath" containing toilet, sink, and shower, although the terms vary from market to market. In some U.S. markets, a toilet, sink, and shower are considered a "full bath." In addition, there is the use of the word "bathroom" to describe a room containing a toilet and a basin, and nothing else.

The design of a bathroom must account for the use of both hot and cold water, in significant quantities, for cleaning the body. The water is also used for moving solid and liquid human waste to a sewer or septic tank. Water may be splashed on the walls and floor, and hot humid air may cause condensation on cold surfaces. From a decorating point of view the bathroom presents a challenge. Ceiling, wall and floor materials and coverings should be impervious to water and readily and easily cleaned. The use of ceramic or glass, as well as smooth plastic materials, is common in bathrooms for their ease of cleaning. Such surfaces are often cold to the touch, however, and so water-resistant bath mats or even bathroom carpets may be used on the floor to make the room more comfortable. Alternatively, the floor may be heated, possibly by strategically placing resistive electric mats under floor tile or radiant hot water tubing close to the underside of the floor surface.

Electrical appliances, such as lights, heaters, and heated towel rails, generally need to be installed as fixtures, with permanent connections rather than plugs and sockets. This minimizes the risk of electric shock. Ground-fault circuit interrupterelectrical sockets can reduce the risk of electric shock, and are required for bathroom socket installation by electrical and building codes in the United States and Canada. In some countries, such as the United Kingdom, only special sockets suitable for electric shavers and electric toothbrushes are permitted in bathrooms, and are labelled as such. UK building regulations also define what type of electrical fixtures, such as light fittings (i.e. how water-/splash-proof) may be installed in the areas (zones) around and above baths, and showers. Contrary to some information provided with bathroom light fittings, sinks and basins do not affect bathroom zones, as a bathroom is solely defined as a room containing a bath or shower, by wiring regulations. It is nevertheless good practice to avoid installing unsuitable fixtures close to sinks, as damage from water splashes may occur.

Bathroom lighting should be uniform, bright and must minimize glare. For all the activities like shaving, showering, grooming etc. one must ensure equitable lighting across the entire bathroom space. The mirror area should definitely have at least two sources of light at least 1 feet apart to eliminate any shadows on the face. Skin tones and hair color are highlighted with a tinge of yellow light. Ceiling and wall lights must be safe for use in a bathroom (electrical parts need to be splash proof) and therefore must carry appropriate certification such as IP44.

All forms of bathroom lighting should be IP44 rated as safe to use in the bathroom.[3]

The first records for the use of baths date back as far as 3000 B.C. At this time water had a strong religious value, being seen as a purifying element for both body and soul, and so it was not uncommon for people to be required to cleanse themselves before entering a sacred area. Baths are recorded as part of a village or town life throughout this period, with a split between steam baths in Europe and America and cold baths in Asia. Communal baths were erected in a distinctly separate area to the living quarters of the village.[citation needed]

Nearly all of the hundreds of houses excavated had their own bathing rooms. Generally located on the ground floor, the bath was made of brick, sometimes with a surrounding curb to sit on. The water drained away through a hole in the floor, down chutes or pottery pipes in the walls, into the municipal drainage system. Even the fastidious Egyptians rarely had special bathrooms.[4]

Virtual reconstruction of the Roman Baths in Weißenburg, Germany, using data from laser scan technology

The Roman attitudes towards bathing are well documented; they built large thermal baths (thermae), marking not only an important social development, but also providing a public source of relaxation and rejuvenation. Here was a place where people could meet to discuss the matters of the day and enjoy entertainment. During this period there was a distinction between private and public baths, with many wealthy families having their own thermal baths in their houses. Despite this they still made use of the public baths, showing the value that they had as a public institution. The strength of the Roman Empire was telling in this respect; imports from throughout the world allowed the Roman citizens to enjoy ointments, incense, combs, and mirrors. The partially reconstructed ruins can still be seen today, for example at Thermae Bath Spa in Bath, England, then part of Roman Britain.

Not all ancient baths were in the style of the large pools that often come to mind when one imagines the Roman baths; the earliest surviving bathtub dates back to 1700 B.C, and hails from the Palace of Knossos in Crete. What is remarkable about this tub is not only the similarity with the baths of today, but also the way in which the plumbing works surrounding it differ so little from modern models. A more advanced prehistoric (15th century BC and before) system of baths and plumbing is to be found in the excavated town of Akrotiri, on the Aegean island of Santorini (Thera). There, alabaster tubs and other bath fittings were found, along with a sophisticated twin plumbing system to transport hot and cold water separately. This was probably because of easy access to geothermic hot springs on this volcanic island.

Both the Greeks and the Romans recognised the value of bathing as an important part of their lifestyles. Writers such as Homer had their heroes bathe in warm water so as to regain their strength; it is perhaps notable that the mother of Achilles bathed him in order to gain his invincibility. Palaces have been uncovered throughout Greece with areas that are dedicated to bathing, spaces with ceramic bathtubs, as well as sophisticated drainage systems. Homer uses the word λοετρά, loetrá, "baths", later λουτρά, loutrá, from the verb λούειν, loúein, to bathe. The same root finds an even earlier attestation on Linear B tablets, in the name of the River Lousios ("bathing" [river]), in Arcadia. Public baths are mentioned by the comedian Aristophanes as βαλανεία, balaneía (sing.: βαλανείον, balaneíon, Latinized as balneum, a "balneary").

Throughout the 16th, 17th, and 18th centuries, the use of public baths declined gradually in the west, and private spaces were favoured, thus laying the foundations for the bathroom, as it was to become, in the 20th century. However, increased urbanisation led to the creation of more baths and wash houses in Britain.

In Japan shared bathing in sento and onsen (spas) still exists, the latter being very popular.

Cultural historian Barbara Penner has written of the ambiguous nature of bathrooms as both the most private space and one most connected to the wider outside world.[5]

Public toilet
–
A public toilet is a room or small building containing one or more toilets which is available for use by the general public, or by customers or employees of certain businesses. Public toilets are commonly separated into male and female facilities, although some can be unisex, increasingly, public toilets are accessible to people with disabilities. Public toilets may either be used free of charge or the user may be charged a fee, in the latter case they are also called pay toilets and sometimes have of a coin-operated turnstile. Public toilets may be provided by the authority or by a commercial business. They may be unattended or be staffed by a janitor or attendant, in many cultures, it is customary to tip the attendant, especially if they provide a grooming service, such as at upscale nightclubs or restaurants. Portable toilets are provided at large outdoor events. In many Asian, African and Muslim countries, public toilets are of the squat type, Public toilets are known by many names in different varieties of English. One of the more formal circumlocutions is public convenience, as in the Guilford Place public conveniences, in American English, restroom usually denotes a toilet facility designed for use by the public. However, bathroom is also commonly used, comfort station sometimes refers to a visitor welcome center such as those found in national parks. In Canadian English, public facilities are always called washrooms, the word toilet generally denotes the fixture itself rather than the room. The word washroom is never used to mean utility room or mud room as it is in parts the United States. Bathroom is generally used to refer to the room in the home contains a bath or shower. In Britain, Australia, Hong Kong, Singapore, and New Zealand, the terms in use are public toilet, public lavatory and more informally, public loo. A bathroom is a room containing a bath, a washroom is a room for washing hands, as public toilets were traditionally signed as Gentlemen or Ladies, the colloquial terms the Gents and the Ladies indicates the facility itself. The British Toilet Association, sponsor of the Loo of the Year Award, in Philippine English, comfort room, or C. R. is the most common term in use. In continental Europe, both toilet, a translation of the French les toilettes, and WC are common, mosques, madrassas and other places Muslims gather, have public sex-segregated wash rooms since Islam requires specific procedures for cleansing parts of the body before prayer. These rooms normally adjoin the toilets, which are subject to Muslim hygienical jurisprudence. Many public toilets are permanent small buildings visible to passersby on the street, others are underground, including older facilities in Britain and Canada

Toilet (room)
–
A toilet, in this sense, is a small room used for privately accessing the sanitation fixture for urination and defecation. Toilet rooms usually include a sink with soap for handwashing, as this is important for personal hygiene and this room is commonly known as a bathroom in American English, a loo in British English, and by many other names across the English-speaking world. Toilet originally referred to personal grooming and came by metonymy to be used for the rooms used for bathing, dressing. It was then used for the similarly private rooms used for urination and defecation. By metonymy, it came to refer directly to the fixtures in such rooms. At present, the word refers primarily to such fixtures and using toilet to refer to the room or activity is somewhat blunt and it is, however, a useful term since it is quickly understood by English-speakers across the world, whereas more polite terms vary by region. Lavatory was common in the 19th century and is broadly understood, although it is taken as quite formal in American English. The contraction lav is commonly used in British English, in American English, the most common term for a private toilet is bathroom, regardless of whether a bathtub or shower is present. Other terms are used, some as part of a regional dialect. Some forms of jargon have their own terms for toilets, including lavatory on commercial airplanes, head on ships, larger houses often have a secondary room with a toilet and sink for use by guests. These are typically known as powder rooms or half baths in North America, the main item in the room is the sanitation fixture itself, the toilet. This may be the sort, which is plumbed into a cistern operated by a ballcock. Or it may be a dry model, which does not need water, the toilet room may also include a plunger, a rubber or plastic tool mounted on a handle, which is used to removing blockages from the toilet drain. Toilets often have a mirror above the sink for grooming, checking ones appearance and/or makeup. Some toilets have a cupboard where cleaning supplies and personal hygiene products may be kept, methods of anal cleansing vary between cultures. If the norm is to use paper, then typically the room will have a toilet roll holder, if instead, people are used to cleaning themselves with water, then the room may include a bidet shower or a bidet. Toilets such as the Washlet, popular in Japan, provide an automatic washing function, the room may also include a plunger, a rubber or plastic tool mounted on a handle, which is used to removing blockages from the toilet drain. If it is a toilet, then the room usually also includes a toilet brush for cleaning the bowl

Public bathing
–
Public baths originated from a communal need for cleanliness at a time when most people did not have access to private bathing facilities. The term public is not completely accurate, as types of public baths are restricted depending on membership, gender, religious affiliation. As societies have changed, the need for public baths has reduced, Public baths have also become incorporated into the social system as meeting places. As the title suggests, public bathing does not refer only to bathing, in ancient times public bathing included saunas, massages and relaxation therapies, comparable to todays spas. The earliest public baths are found in the ruins in of the Indus Valley Civilization, the bath is housed inside a larger—more elaborate—building and was used for public bathing. The Great Bath and the house of the priest suggest that the Indus had a religion, later gymnasia had indoor basins set overhead, the open maws of marble lions offering showers, and circular pools with tiers of steps for lounging. Bathing was ritualized, becoming an art – of cleansing sands, hot water, hot air in dark vaulted vapor baths, a cooling plunge, cities all over Ancient Greece honored sites where young ephebes stood and splashed water over their bodies. The first public thermae of 19 BC had a rotunda 25 metres across, circled by small rooms, set in a park with artificial river and pool. By AD300 the Baths of Diocletian would cover 140,000 square metres, its soaring granite, Roman baths became something like a cross between an aquacentre and a theme park, with pools, game rooms, gardens, even libraries and theatres. One of the most famous public bath sites is Aquae Sulis in Bath and he also states that In Western Europe only the Finns still practice a truly public bathing habit. Dr. Fagan has done research on public bathing. During the Ottoman Empire public baths were widely used, the baths had both a religious and popular origin deriving from the Quran and the use of steamrooms by the Turks. The Turkish baths also known as the Hammam, was considered a place for gathering in Turkish Culture. The process of Hammam is very similar to that of the Roman bathing, the origin of Japanese bathing is Misogi, ritual purification with water. After Japan imported Buddhist culture, many temples had saunas, which were available for anyone to use for free, in the Heian period, houses of prominent families, such as the families of court nobles or samurai, had baths. The bath had lost its religious significance and instead became leisure, Misogi became Gyōzui, to bathe in a shallow wooden tub. In the 17th century, the first European visitors to Japan recorded the habit of daily baths in sexually mixed groups. Before the mid-19th century, when Western influence increased, nude bathing for men, women

Shower
–
A shower is a place in which a person bathes under a spray of typically warm or hot water. Indoors, there is a drain in the floor, most showers have temperature, spray pressure and adjustable showerhead nozzle. The simplest showers have a swivelling nozzle aiming down on the user and this allows the showerer to spray the water at different parts of their body. A shower can be installed in a shower stall or bathtub with a plastic shower curtain or door. Showering is common in Western culture due to the efficiency of using it compared with a bathtub and its use in hygiene is therefore common practice. A shower uses less water on average than a bath,80 litres for a shower compared with 150 litres for a bath, the original showers were neither indoor structures nor man-made, but were common natural formations, waterfalls. The falling water rinsed the bathers completely clean and was more efficient than bathing in a traditional basin, ancient people began to reproduce these natural phenomena by pouring jugs of water, often very cold, over themselves after washing. There has been evidence of upper class Egyptian and Mesopotamians having indoor shower rooms where servants would bathe them in the privacy of their own homes. However, these were rudimentary by modern standards, having rudimentary drainage systems and water was carried, not pumped, the ancient Greeks were the first people to have showers. Their aqueducts and sewage systems made of lead pipes allowed water to be pumped both into and out of large communal shower rooms used by elites and common citizens alike. These rooms have been discovered at the site of the city Pergamum, the depictions are very similar to modern locker room showers, and even included bars to hang up clothing. The ancient Romans also followed this convention, their famous bathhouses can be all around the Mediterranean. The Romans not only had these showers, but also believed in bathing multiple times a week, the water and sewage systems developed by the Greeks and Romans broke down and fell out of use after the fall of the Roman Empire. The first mechanical shower, operated by a pump, was patented in England in 1767 by William Feetham. His shower contraption used a pump to force the water into a vessel above the users head, the system would also recycle the same dirty water through every cycle. This early start was greatly improved in the anonymously invented English Regency shower design of circa 1810, the original design was over 10 feet tall, and was made of several metal pipes painted to look like bamboo. A basin suspended above the pipes fed water into a nozzle that distributed the water over the users shoulders, the water on the ground was drained and pumped back through the pipes into the basin, where the cycle would repeat itself. The original prototype was improved upon in the following decades

Folding screen
–
A folding screen is a type of free-standing furniture. It consists of frames or panels, which are often connected by hinges or by other means. It can be made in a variety of designs and with different kinds of materials, folding screens have many practical and decorative uses. It originated from ancient China, eventually spreading to the rest of East Asia, Europe, screens date back to China during the Eastern Zhou period. These were initially one-panel screens in contrast to folding screens, folding screens were invented during the Han dynasty. Depictions of those folding screens have been found in Han-era tombs, a folding screen was often decorated with beautiful art, major themes included mythology, scenes of palace life, and nature. It is often associated with intrigue and romance in Chinese literature, for example, an example of such a thematic occurrence of the folding screen is in the classical novel Dream of the Red Chamber by Cao Xueqin. The folding screen was an element in Tang literature. The Tang poet Li He wrote the Song of the Screen, the folding screen surrounded the bed of the young couple, its twelve panels were adorned with butterflies alighted on China pink flowers, and had silver hinges resembling glass coins. Folding screens were made from wooden panels and painted on lacquered surfaces. Even though folding screens were known to have used since antiquity. During the Tang dynasty, folding screens were considered ideal ornaments for many painters to display their paintings, many artists painted on paper or silk and applied it onto the folding screen. There were two distinct artistic folding screens mentioned in literature of the era. One of it was known as the huaping and the other was known as the shuping and it was not uncommon for people to commission folding screens from artists, such as from Tang-era painter Cao Ba or Song-era painter Guo Xi. The landscape paintings on folding screens reached its height during the Song dynasty, folding screens became significant during the period of Unified Silla. Folding screens known as irworobongdo were important elements in the room of some Joseon kings. Like many Japanese arts and crafts, folding screens originated in China, according to the 8th-century work Nihon Shoki, one of the earliest folding screens to reach Japan was during the reign of Emperor Tenmu, which were gifts from the Korean kingdom of Silla. By the 8th century, folding screens became well known in Japan through China during the Tang dynasty, during the late Muromachi period, the Japanese began depicting everyday life on folding screen, which was a custom imported from China

Hygiene
–
Hygiene is a set of practices performed for the preservation of health. According to the World Health Organization, Hygiene refers to conditions and practices help to maintain health. Some regular hygienic practices may be considered good habits by a society while the neglect of hygiene can be considered disgusting, in ancient Greek religion, Hygeia was the personification of health, cleanliness and hygiene. Hygiene is a related to cleanliness, health and medicine. In medicine and in home and everyday life settings, hygiene practices are employed as preventative measures to reduce the incidence, the terms cleanliness and hygiene are often used interchangeably, which can cause confusion. In general, hygiene mostly means practices that prevent spread of disease-causing organisms, since cleaning processes remove infectious microbes as well as dirt and soil, they are often the means to achieve hygiene. Other uses of the term appear in phrases including, body hygiene, personal hygiene, sleep hygiene, mental hygiene, dental hygiene, Hygiene is also the name of a branch of science that deals with the promotion and preservation of health, also called hygienic. Hygiene practices vary widely, and what is considered acceptable in one culture might not be acceptable in another, medical hygiene pertains to the hygiene practices related to the administration of medicine, and medical care, that prevents or minimizes disease and the spreading of disease. Medical hygiene practices include, Isolation or quarantine of persons or materials to prevent spread of infection. Sterilization of instruments used in surgical procedures, use of protective clothing and barriers, such as masks, gowns, caps, eyewear and gloves. Proper bandaging and dressing of injuries, Some procedures were refined in response to late-20th century disease outbreaks, notably AIDS and Ebola. Hygiene in home and everyday life settings plays an important part in preventing spread of infectious diseases. It includes procedures used in a variety of situations such as hand hygiene, respiratory hygiene, food and water hygiene, general home hygiene, care of domestic animals. At present, these components of hygiene tend to be regarded as separate issues, preventing the spread of infectious diseases means breaking the chain of infection transmission. The simple principle is that, if the chain of infection is broken, targeted hygiene is based on identifying the routes of spread of pathogens in the home, and applying hygiene procedures at critical points at appropriate times to break the chain of infection. The main sources of infection in the home are people, foods and water, germs are constantly shed from these sources via mucous membranes, faeces, vomit, skin scales, etc. Thus, when circumstances combine, people become exposed, either directly or via food or water, the main highways for spread of germs in the home are the hands, hand and food contact surfaces, and cleaning cloths and utensils. Germs can also spread via clothing and household linens, such as towels, safe disposal of human waste is a fundamental need, poor sanitation is a primary cause of diarrhea disease in low income communities

Toilet
–
A toilet is a sanitation fixture used for the storing or disposal of human urine and feces. In developed countries, different forms of flush toilets are common. These are connected to a system in most urban areas. In many developing countries, especially in areas, dry toilets such as pit latrines. Dry toilets are usually placed in outhouses, i. e. not inside the dwelling, in many countries, private homes are designed with the flush toilet and the bath or shower in the same room, the bathroom, to simplify plumbing and reduce cost. Other cultures find this insanitary, and have one room for body-washing, public toilets are installed where their use is expected on a permanent basis, while portable toilets may be brought in for large but temporary gatherings. Chemical toilets are used in various contexts, such as passenger trains. Serious waterborne diseases such as cholera and diarrhea occur when open defecation or poor sanitation permits human waste to pollute water supplies, historically, sanitation has been a concern from the earliest stages of human settlements. The Indus Valley Civilization is particularly notable for its extensive sanitation works, for the most part, early cities emptied their waste into rivers or seas manually or via open ditches. Sanitation in ancient Rome was notably advanced, as were some of the reredorters of medieval monasteries, a precursor to the modern flush toilet system was designed by John Harington in 1596 but did not become common until the late 19th century. Even London, at time the worlds largest city, did not require indoor toilets in its building codes until after the First World War. A typical flush toilet is a ceramic bowl connected on the up side to a cistern that enables rapid filling with water, when a toilet is flushed, the sewage should flow into a septic tank or into a system connected to a Sewage treatment plant. However, in countries, this treatment does not happen. The water in the bowl is connected to a pipe shaped like an upside-down U. One side of the U channel is arranged as a tube longer than the water in the bowl is high. The siphon tube connects to the drain, the bottom of the drain pipe limits the height of the water in the bowl before it flows down the drain. The water in the acts as a barrier to sewer gas entering the building. Sewer gas escapes through a vent pipe attached to the sewer line, the amount of water used by conventional flush toilets usually makes up a significant portion of personal daily water usage

Sink
–
A sink—also known by other names including sinker, washbowl, hand basin and wash basin—is a bowl-shaped plumbing fixture used for washing hands, dishwashing, and other purposes. Sinks have taps that supply hot and cold water and may include a feature to be used for faster rinsing. They also include a drain to remove used water, this drain may itself include a strainer and/or shut-off device, Sinks may also have an integrated soap dispenser. When a sink becomes stopped-up or clogged, a person will often resort to use a chemical drain cleaner or a plunger, the washstand was a bathroom sink made in the United States in the late 18th century. The washstands were small tables on which were placed a pitcher, sometimes the table had a hole where the large bowl rested, which led to the making of dry sinks. From about 1820 to 1900 the dry sink evolved by the addition of a cabinet with a trough built on the top. This is where the bowls or buckets for water were kept, splashboards were sometimes added to the back wall, as well as shelves and drawers, the more elaborate designs usually placed in the kitchen. Sinks are made of different materials. These include, Stainless steel is used in kitchens and commercial applications because it represents a good trade-off between cost, usability, durability, and ease of cleaning. Most stainless steel sinks are made by drawing a sheet of steel over a die. Some very deep sinks are fabricated by welding, Stainless steel sinks will not be damaged by hot or cold objects and resist damage from impacts. Enamel over cast iron is a material for kitchen and bathroom sinks. Heavy and durable, these sinks can also be manufactured in a wide range of shapes. Aggressive cleaning will dull the surface, leading to more dirt accumulation, enamel over steel is a similar-appearing but far less rugged and less cost-effective alternative. Solid ceramic sinks have many of the characteristics as enamel over cast iron. Plastic sinks come in basic forms, Inexpensive sinks are simply made using injection-molded thermoplastics. These are often deep, free-standing sinks used in laundry rooms, subject to damage by hot or sharp objects, the principal virtue of these sinks is their low cost. High-end acrylic drop-in and undermount sinks are becoming popular, although they tend to be easily damaged by hard objects - like scouring a cast iron frying pan in the sink

9.
Bathtub
–
A bathtub, bath, or tub is a large or small container for holding water in which a person or a persons pet may bathe. Most modern bathtubs are made of thermoformed acrylic, porcelain enameled steel, fiberglass-reinforced polyester, a bathtub is usually placed in a bathroom either as a stand-alone fixture or in conjunction with a shower. Modern bathtubs have overflow and waste drains and may have taps mounted on them and they are usually built-in, but may be free-standing or sometimes sunken. Until recently, most bathtubs were roughly rectangular in shape but with the advent of acrylic thermoformed baths, bathtubs are commonly white in colour although many other colours can be found. The process for enamelling cast iron bathtubs was invented by the Scottish-born American David Dunbar Buick, two main styles of bathtub are common, Western style bathtubs in which the bather lies down. These baths are typically shallow and long, eastern style bathtubs in which the bather sits up. These are known as ofuro in Japan and are typically short, evidence of the earliest surviving personal sized bath tub was found on the Isle of Crete where a 1. 5-metre long pedestal tub was found built from hardened pottery. The design spread to England where it found much popularity among the aristocracy, early bathtubs in England tended to be made of cast iron, or even tin and copper with a face of paint applied that tended to peel with time. The Scottish-born inventor David Buick invented a process for bonding porcelain enamel to cast iron in the 1880s while working for the Alexander Manufacturing Company in Detroit. Far from the feet and luxury most associated with clawfoot tubs, an early Kohler example was advertised as a horse trough/hog scalder. The items use as hog scalder was considered an important marketing point than its ability to function as a bathtub. In the latter half of the 20th century, the once popular clawfoot tub morphed into a tub with a small apron front. This enclosed style afforded easier maintenance and, with the emergence of colored sanitary ware, more options for the homeowner. The Crane Company introduced colored bathroom fixtures to the US market in 1928, the clawfoot tub or claw-foot tub was considered a luxury item in the late 19th century, originally made from cast iron and lined with porcelain. Modern technology has contributed to a drop in the price of clawfoot tubs, clawfoot tubs usually require more water than a standard bathtub, because generally they are larger. Clawfoot tubs come in 4 major styles, Classic roll rim tubs, slipper tubs - where one end is raised and sloped creating a more comfortable lounging position. Double slipper tubs - where both ends are raised and sloped, double ended tubs - where both ends of the tub are rounded. Notice how one end of the tub is rounded and one is fairly flat

Pit latrine
–
A pit latrine or pit toilet is a type of toilet that collects human feces in a hole in the ground. They use either no water or one to three liters per flush with pour-flush pit latrines, when properly built and maintained they can decrease the spread of disease by reducing the amount of human feces in the environment from open defecation. This decreases the transfer of pathogens between feces and food by flies and these pathogens are major causes of infectious diarrhea and intestinal worm infections. Infectious diarrhea resulted in about 700,000 deaths in children under five years old in 2011 and 250 million lost school days, pit latrines are the lowest cost method of separating feces from people. A pit latrine generally consists of three parts, a hole in the ground, a slab or floor with a small hole. The shelter is known as an outhouse. The pit is typically at least 3 meters deep and 1 m across, the World Health Organization recommends they be built a reasonable distance from the house balancing issues of easy access versus that of smell. The distance from groundwater and surface water should be as large as possible to decrease the risk of groundwater pollution, the hole in the slab should not be larger than 25 centimeters to prevent children falling in. Light should be prevented from entering the pit to reduce access by flies and this may require the use of a lid to cover the hole in the floor when not in use. When the pit fills to within 0.5 meters of the top, it should be emptied or a new pit constructed. Fecal sludge management involves emptying pits as well as transporting, treating and using the fecal sludge. If this is not carried out properly, water pollution and public health risks can occur, a basic pit latrine can be improved in a number of ways. One includes adding a pipe from the pit to above the structure. This improves airflow and decreases the smell of the toilet and it also can reduce flies when the top of the pipe is covered with mesh. In these types of toilets a lid need not be used to cover the hole in the floor. Other possible improvements include a floor constructed so fluid drains into the hole, as of 2013 pit latrines are used by an estimated 1.77 billion people. This is mostly in the world as well as in rural. In 2011 about 2.5 billion people did not have access to a proper toilet, southern Asia and Sub-Saharan Africa have the poorest access to toilets

Turkish bath
–
A Turkish bath is the Islamic variant of the Roman bath, steambath, sauna, or Russian banya, distinguished by a focus on water, as distinct from ambient steam. In Western Europe, the Turkish bath as a method of cleansing, the process involved in taking a Turkish bath is similar to that of a sauna, but is more closely related to ancient Greek and ancient Roman bathing practices. The Turkish bath starts with relaxation in a room that is heated by a flow of hot, dry air. Bathers may then move to an even hotter room before they wash in cold water, after performing a full body wash and receiving a massage, bathers finally retire to the cooling-room for a period of relaxation. The difference between the Islamic hammam and the Victorian Turkish bath is the air, the hot air in the Victorian Turkish bath is dry, in the Islamic hammam the air is often steamy. The bather in a Victorian Turkish bath will often take a plunge in a pool after the hot rooms. In the Islamic hammams the bathers splash themselves with cold water and it is not wet air, nor moist air, nor vapoury air, it is not vapour in any shape or form whatever. It is an immersion of the body in hot common air. One of the Five Pillars of Islam is prayer and it is customary before praying for Muslims to perform ablutions. The two Islamic forms of ablution are ghusl, a cleansing, and wudu, a cleansing of the face, hands. In the most extreme of cases, cleansing with pure soil or sand is also permissible, often, hammams are located close to mosques and other places for prayer for those who wish to perform deeper cleansing. Islamic hammams, particularly in the Moroccan case, evolved from their Roman roots to adapt to the needs of ritual purification according to Islam, for example, in most Roman-style hammams, one finds a cold pool for full submergence of the body. The style of bathing is less preferable in the Islamic faith, for al-Ghazali, the hammam is a primarily male experience, and he cautions that women are to enter the hammam only after childbirth or illness. Even then al-Gazali finds it admissible for men to prohibit their wives or sisters from using the hammam, the major point of contention surrounding hammams in al-Ghazalis estimation is nakedness. In his work he warns that overt nakedness is to be avoided, … he should shield it from the sight of others and second, guard against the touch of others. He focuses extensively in his writing on the avoidance of touching the penis during bathing and he writes that nakedness is decent only when the area between the knees and the lower stomach of a man are hidden. For women, exposure of only the face and palms is appropriate, according to al-Gazali, the prevalence of nakedness in the hammam could incite indecent thoughts or behaviours and so it is a controversial space. Ritual ablution is also required before or after sexual intercourse, during those centuries of war, peace, alliance, trade and competition, the two cultures had tremendous influence on each other
